Specification of Letters Patent;

Patented Oct. 6, 1914:.

Application filed June 13, 1912. Serial No. 703,476. I

Swampscott, in thetcounty of Essex and State of Massachusetts, have invented certam Improvements 1n Machlnes for Use in the Manufacture of Boots and Shoes, of

whichthe following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. I

This invention relates to machines for use in the manufacture of boots and shoes and particularly to shoe shaping machines. The inventionv is herein shown as embodied in a shoe beatingmachine, andthis application is a continuation of my application Ser. No. 406,213, filed Dec. 12, 1907, which matured June 25, 1912 into Letters Patent No. 1,030,837, as to subject matter common to this application and to said application Ser. No. 406,213. The machine shown in the said prior application comprises a rotary beater which has a rapidly rotating carrier or hub having annular end disks, between which disks extend stems or rods arranged around the peripheryof the carrier and supporting a series of beating elements which strike a very rapid succession of light blows. The beating elements specifically claimed therein comprise rings loosely strung on their supporting rods so that, during the rotation, of the carrier, the rings are held out radially therefrom by centrifugal force in normal operative position while, under pressure of the work, the rings are capable both of swinging or turning about their pivots and of yielding inwardly. 1

Rotary shoe beating machines of this type are employed with greatsuccess in pounding up the overlasted marginal portions of shoe upper along the edges of the shoe bottom. While the beating elements ofthe said machine are from their above outlined construction and mounting Well adapted to conform to the surface of the work presented to them and are eflicient in'pounding up and smoothing the work, I have discovered that certain advantages may be obtainedby a construction and mounting of beating elements such that, in addition to the above mentioned movements, the beating elements may have movements inotherdirections, in-

eluding a sidewise movement through displacement in a direction lengthwise of the carrier as they strike the work. i I

In accordance with the present invention, the beating elements comprise blocks loosely confined against dislodgment fromthe rotary carrier by centrifugal force and constructed and arranged with relation to the said carrier to have a practically universal turning and swinging movement as they strike the work, in addition to capacityfor yielding inwardly under pressure of the ortipping backwardly as they strike the work and rub over it.

The machine also comprises other instru mentalities for treating a shoe, besides the beatlng roll, including a smoothing or irontion consists in improved shoe supporting and gulding means particularly adapted to cooperatewith these beating and smoothing rolls. A work guide which I have found particularly adapted for cooperation with the beating roll while the latter 1s treating the bottom of the shoe comprises a work resting table or plate which is normally disposed horizontally and can tip about an axis parallel with the axis of the roll. A115 other work guide, which I have found paringroll and another feature of this inventicularly adapted for cooperation with the smoothing roll by pressingthe side of the shoe against said roll and which may also be used with advantage to press either the side or the bottom of the shoe against the.

face of the beating roll, comprises a work resting plate or bar that is also pivoted against the roll. Either or both rests may be vibrated and thereby caused to effect a light beating action upon the surface of the shoe engaged thereby. Herein, the work resting table isshown as vibrated, being held yieldingly away from the vibrator when the 1100 the roll while the bar presses the shoe.

work is not pressed against it, and it :will

be obvious that similar vibrating means could be applied to the work resting bar. 'It will also be observed that the action of the beating roll upon the shoe produces a vibration of the shoe against the supporting face of the shoe resting means by which the surface of the shoe engaged by said resting means is lightly beaten whether or not the resting means is vibrated. The beating ac tion of the shoe resting means is particularly advantageous and the cooperation of the resting means and the rolls is conspicuously apparent, when a lasted welt shoe is presented with a side face against the roll and with that port-ion of its bottom face over which the welt is to be applied against the resting means. The vibration of the resting means,

or of the shoe, then beats the upper firmly against the feather of the innersole lip. The resting plate or bar may advantageously have a formation to adapt it to beat the upper into the angle between the feather and the lip of the innersole to form there a seat for the welt. It is obvious that work resting plates or bars having formations adapted for the particular work to be done may be used exchangeably incooperation with the 7 ,rolls for treating the sides of the shoe.

These and other novel features of the present invention, including certain combinations of parts and details of construction, will be apparent from the following de tailed description read in connection with the accompanying drawings in which Figure l is an angular perspective in elevation of portions of the machine concerned with the present invention; Fig. 2 is an end view in elevation and partly in section of the machine showing two positions in which the work is presented for beating the forepart of a McKay shoe; Fig. 3 is a detail of one of the beating elements; Fig. 4 is a side elevation partly in section of a portion of the machine showing a position of the work for beating the rear part of the shoe while using the work rest that is illustrated in F ig. 1 for supporting the forepart; Fig. 5 is a detail showing a work resting plate particularly adapted for welt shoes and its operative relation to the heater and a welt shoe forepart; Fig. 6 is an angular perspective of the work resting plate on a larger scale and looking at the bottom of the plate; Fig. 7 is an angular perspective in elevation and on a similar scale of the support on which said plate may be hinged; Fig. 8 is an angular perspective of another form of work supporting means, looking at the work support from below;-Fig. 9 is a vertical section through the smoother roll, showing an operative relation of said roll and the co operating shoe resting means to a shoe; Fig. 10 is an extension of the left hand end of Fig. 1, the angle being changed to increase the disclosure; Fig. 11 is an end elevation particularly to show the features illustrated in Fig. 1. I

Bearings 2 on the frame of the machine support a shaft 4 operated through suitable connections to a source of power and upon which is mounted the shoe beating and finishing rolls with which this invention has to do, including a hub or carrier having end disks or flanges 6. The end disks 6 are connected by rods 8 which support an annular series of beating members, each comprising a plurality of beating elements 40.

The beating elements 40, in accordance with a feature of the present invention, somewhat resemble dumb-bells in shape, having at their outer ends rounded heads 42 (Figs. 2 and 3), the outer faces of which con stitute work engaging surfaces, and having at their inner ends ball shaped flanges 45. Reduced necks 44 connect the heads 42 and the flanges 45. The beating elements 40 are loosely confined between adjacent rods 8 ar ranged on opposite sides of the necks 44. The heating elements are thus free during rotation of the carrier to be moved outwardly under the action of centrifugal force but are prevented from being thereby dislodged from the carrier by reason of their flanges 45. While the heating elements 40 are thus held outwardly their above-described construction and mounting permits them, under pressure of the work, to yield inwardly, radially or otherwise. Moreover, the ball shaped flanges 45, in connection with the supporting rods 8, constitute the substantial equivalents of ball and socket joints and permit practically universal turning or swinging movement of the beating elements, so that the beating elements not only may swing backwardly as they strike the work and yield inwardly, but are also capable of having a sidewise or lateral movement lengthwise of the carrier in either direction.

As shown in Figs. 1 and 2, the above described rotary beater may be advantageously employed for beating the bottom of a shoe in conjunction with a side beater comprising a plate 10 connected with suitable operating mechanism. and arranged to extend into close proximity to the beating elements 40 where it is adapted to engage the side of the shoe close to the edge of the shoe bottom.

In addition to the upper beating roll, which will preferably be constructed with beating elements 40 as above described, the machine comprises an upper smoothing roll 11 which will preferably have the contour shown in Figs. 1 and 10 to adapt it particularly for treating various portions of the sides and top of the shoe.-

Cooperating with the upper beating and smoothing rolls are means for resting the shoe in position to receive'progressively the action of said rolls on one side of the shoe while the shoe is advanced along and, it may be, actively treated by the resting means, which will preferably be hinged to tip toward and from the rolls about an axis substantially parallel with the: axis of the rolls. In Figs. 1, 2, 1, Sand 6 the resting means cooperating with the beating roll is shown as comprising a tipping plate 12, and in Figs. 1,

9, 10 and 11 the resting means cotiperating.

ing a raised abutment which constitutes the actual work resting face, as in Fig. 5 (see also Fig. 8) for welt work, the face inthe latter case engaging the shoe bottom between the edge and the lip of the welt innersole to assist in forming the upper upon the feather of the innersole to provide a good seat for the welt with which the shoe is later to be provided. Preferably, and as shown, the tipping plate 12 hasassociated with it a stop 46 arranged to limit the extent of tipping movement of the plate 12. The shoe resting bar 13 (Fig. 9) isadapted similarly to support and act on a shoe while it is being treated by the roll 11, or it might be by the beating roll. Provision is made for vibrating the work rest in a direction substantially perpendicular to the supported surface of the shoe to cause it to act more effectively in forming the shoe stock. The vibrating means is illustrated as applied to the resting plate 12 andit will be obvious that it may be similarly applied to the resting bar 13.

The stem 16 can slide in a sleeve 18 and be depressed when desired, against the action of a spring 20, intothe path of a continuously running cam 26 on a counter shaft 28 mounted in bearings 30 and driven by a pulley 32 and a belt from a pulley 34 on the high-speed shaft 36 from which the side beater 10 is vibrated. the elevation of the stem. 16 by the spring 20 and an adjustable stop: 38 limits thedepression of the stem and may be setto hold the stem of the rest out of the path of the cam 26, if vibration of the rest is not desired. It may be noted that the action of the beating elements 40 produces some vibration of the shoe against the rest and thereby increases the smoothing effect of the rest upon the surface engaged by it. Fur-. thermore, the heating elements 40 have operative movement in a direction to work the upper stock toward the edge formed by the side and bottom faces of the shoe. This ac tion of the heating elements 40 in conjunction The collar 37 limits with the co'ciperating vibratory action of the rest when that rest isvibrated results in forming between the side and bottom faces of the shoe the well defined angular edge whichis so important in the finished shoe The rest shown in Fig. 8 maybe substituted for that shown in Fig. 4, the stems being alike, and the shoeresting plate in Fig. 8 is not hinged but is adjustable horizontally on the head of its stem and the contour of its shoe resting surface is made to adapt it particularly to l the work illustrated in Fig. 5, or that indicated in Fig. 4. The work resting bar 13 of Figs. 9, 10 and 11 is a convenient embodi ment of the invention for use with the smoothing roll 11, which it is customary to make of irregular tapering formation as appears in Fig. 10 because it can be more readily adapted to suit the configuration of the roll than can the plate 12. Theshoe resting bar 13 is shown as having twostems 66 which are adjustably clamped in blocks.

68 by bolts 70 to permit adjustment lengtlr. wise of the stems. The blocks 68 can turn on a rod 82 which is encircled by a sleeve 72 that is clamped against turning in support 7 6 by a binding screw 77. A torsion spring 84: has one end connected to one block 68 and the other to the sleeve and yieldingly upholds the shoe resting bar 13 to a position determined by a stop screw 86 that is carried by a fixed rod 90 and engages an ear on the upper end of one block 68 as shownin Figs. 10 and 11. The support 76 is adjustable, angularly about a rod .78 that is located back of the rod 13 and projects from a portion of the frame 2.. The specific construction and mounting of this shoe resting means is not herein claimed but will be claimed in a separate application. r

In the use of the machine, the shaft 4 and the rolls andother driven parts beinginmotion, a shoe maybe presented in positions 1 such as indicated in the several figures of the drawings and turned and advanced until all parts requiring treatment have been subjected to the action of the beating roll and of the smoothing roll for pounding upand blocking the shoe as its condition may require. If the shoe isa welt shoe, the resting plate 12 of Fig. flwill advantageously be used rather than thatshown in Fig. 2to shape the upper to the feather of the innersole, and it may be into the angle between the feather an the lip, without crushing, the innersole lip. If beating by means of the shoe resting plate (Figs. 1,5 or 8) is desired, the stop screw 38 will be lowered to allow the stem 16 to be depressed into the path of the cam 26. When the shoe has been beaten the operator shifts it} to the smootlr ing roll 11, resting it on the bar 13 as in Figs. 9 and 11 to cause the sides and top faces ofthe shoe to be treated byrubbing action in the direction desired, either toward the edge as in Fig. 9 or'lengthwiseof the edge as in Fig. 11. In the latter treatment the shoe can be thrust toe first between the bar and the roll to treat one side as in dotted lines in. Fig. 11, the spring 84 yielding and serving to press the shoe upwardly against the roll while the shoe is in that position in which the operator lea-st advantageously applies such pressure, and then can be withdrawn and advanced in its full line position for treatment of its other side while the operator presses the shoe downwardly. The type of machine to which this invention relates is identified in the claims as a shoe shaping machine and the beating and smoothing rolls are sometimes identified as shoe shaping rolls but without any intention to exclude shoe making and finishing machines having rolls or tools, the operations of which may not be strictly described as giving shape to a shoe.
